Turbine flowmeter with a simple structure, lightweight, high precision, good reproducibility, responsive, easy installation and maintenance features, the new generation of flow meter flow meter in the main types.
When the measured fluid flow through the turbine flowmeter sensor, the role of the fluid, the impeller under the force of rotation, the speed and the average flow velocity is proportional to the same time, the blade periodically cut electromagnets magnetic field lines, changing the magnetic flux coil, According to the principle of electromagnetic induction, in the coil will sense the pulse of the potential signal, the electrical pulse signal, the electrical pulse signal frequency is proportional to the measured fluid flow.
Turbine flow sensor and display instrument supporting the composition. Sensors with high precision, good repeatability, long life and simple operation and so on. Can be widely used in petroleum, chemical, metallurgy, paper and other industries to measure the volume of liquid instantaneous volume and volume. Turbine flowmeter and some of the scene can not be applied to the situation: with impurities and more fluid: such as circulating cooling water, river water, sewage water, fuel, etc .; rapid changes in the flow of places, such as boiler water supply system, air hammer air supply system ; Measurement of liquid, the pipeline pressure is not high and the flow is large, the instrument downstream pressure may be close to the saturated vapor pressure, there is the risk of cavitation, such as liquid ammonia from the high slot by bit free flow, Installation; welding machine, motor, there are contacts near the relay, there are serious places of electromagnetic interference; straight pipe length of a serious shortage of upstream and downstream, such as the ship's cabin; automatic boiler water supply system, such as pump and pump stop frequently , Impeller impingement, the turbine flowmeter sensor quickly damaged; corrosive or abrasive media selection should be careful.
